Hello all. I am new here and was looking at the KVS tool (not purchased yet) to find upgradable seat. I have a few general questions.
So I have 19350 miles on Mileage Plus card and wanted to book a ticket with a one way upgrade. I need to fly SFO-WAW anytime during summer-september for 1 month+ stay. I just purchased 1K additional miles to get to 20000 mark and will have 20350 miles in about 48 hours. My question is how to search for partially upgradable ticket? Is it possible with KVS? Will it also show me fares for upgradable seats on Star Alliance? What kind of membership would be best for me? And, lastly, if I locate the fare through KVS tool how do I book? Do I call travel agent or star alliance directly? Thanks a lot!
p.s. I will fly with a 1 yo if that matters and that is why I really could use an upgrade
